SPECIFICATIQN forming part of Letters Patent No. 689,121, dated December17, 1901.

Application filed May 24, 1901. Serial No. 61,722. (No model.)

To @ZZ whom t may concern:

13e it known that I, BENJAMIN JQPIQUET, a citizen of the United States,and a resident of 1Woodbury, in the county of Nassau and State cf NewYork, have invented a new and Improved Tire-Repairing Tool, ot' whichthe following is a full, clear, and exact description.

The purpose of the invention is to provide a tool especially adapted forrepairing punctures in pneumatic tires and to so construct the tool thatit may be used to enlarge a puncture and to introduce through theenlarged puncture an ordinary plug or, preferably, a plug having adouble head and a short connecting-shank, the shank being adapted tofill the enlarged aperture and the heads to close in contact Withtheinner and ou ter faces of the tire around the aperture in an air-tightmanner.

A further purpose of the invention is to construct the tool in a simpleand durable manner and so that it will be light, strong, of small size,and capable of convenient and ready manipulation.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section through the device, illustrating it inposition to enlarge a puncture in a tire. Fig. 2 is a view similar toFig. 1, the body of the tool being reversed and the plug being shown inposition in its carrier to be engaged by the introducingsections of thetool. Fig. 3 is a vertical section through the tool, illustrating itsapplication to a tire and a plug as partly in position in the apertureof the tire. Fig. 4 is an edge View of the improved tool, the partsbeing in the position shown in Fig. 1 and the plug being shown in thereceiver. Fig. 5 is a vertical section-through the improved form ot plugespecially adapted for use in connection with the tool, and Fig. 6 is aside elevation of the ordinary form of plug.

The frame consists of two plates 10 and 11, having ears or oitsets 12and 13 at opposite sides. An eccentric 14 is pivoted by a pin 14abetween the ears 12, which eccentric is provided With a handle 15. Apinion 16 is pivoted by a pin 161 between the ears 13, having anintegral or attached handle 17. A bar18 is located between the plates l0and 1l. This bar extends longitudinally ot the frame formed by the saidplates 10 and 11, and its outer longitudinal edge is engaged near thefree end of the bar by the eccentric 14, the opposite end of the barbeing pivoted to the frame at the end opposite the end carrying the saidears. at the free end cf the bar 18, having a convexed outer and aconcaved inner face, together with a sharp or cutting edge 2O at itsouter end. When the eccentric 14 is moved in a manner to bring itslarger portion in contact with the bar 18, as shown in Fig. 3, the baris held longitudinally straight in the frame; but when the smallerportion of the eccentric engages with the bar 18 said bar may be swungoutward at its free end, as shown in Fig. 2. A second bar 2l is locatedin the frame, having end or longitudinal movement between the plates 10and 11. The sliding bar 21 is parallel with the pivoted bar 18 when thelatter is forced inward by its eccentric. The sliding bar 21 is providedwith a longitudinal slot 22, and guide-pins 23, connecting the plates 10and 11, are loosely passed through the said slot. The sliding bar 21 isprovided with a jaw 24 at what may be termed its outer end. The said jawcorresponds to the jaw 19 of the pivoted bar 18, being provided with asharp or cutting outer end 25, and the outer face ot the jaw 24 isconvexed and its inner face concaved. When the two jaws 19 and 24 arebrought together, they form a tubular punch, asis shown in Fig. 1. Aseries of teeth 26 A tapering jaw 19 is formed" The side members of ayoke 27 are connected by pivot-pins 29 to the outer side portions of theframe, and the yoke extends some distance beyond the ends of the frame.In fact the frame can be turned end for end in the yoke. The upper orbow portion a. of the yoke is of less width than the other portions, asshown in Fig. 4, and the reduced section a of the yoke constitutes areceiver for a plug used in making a repair. The plug is made of softrubber, and the preferred form A of the plug is shown in Fig. 5. Thisform of plug consists of two opposing heads 30 and 3l, connected by ashank 32. The outer faces of the heads are conveXed j and their innerfaces more or less straight;

but Vthe inner face of what is intended to be the outer head of theplug, or that which `is over t-he bore, is provided with an annularrecess or cavity 33, so that the inner face of the outer head willclosely adapt itself to the convexed outer face of the tire when theplug is placed in position on the tire by the tool. In Fig. 6 I haveillustrated the ordinary form of plug A', consisting of a shank or stem34 and a conical head 35.

In operation the handles of the eccentric and pinion are carried upward,whereupon the-bar 18 is held in the frame against side movement in anoutward direction and against the sliding bar 21, and the jaws of thetwo bars will extend the same distance beyond an end of the frame and inclose contact with each other, forming a tubular punch. This punch isthen introduced into the tire at the puncture to produce a clearroundaperture, as shown in Fig. l. The aperture having been made, thejaws are drawn from. the tire and the frame is turned end for end in theyoke. Thepinion is now turned until the jaw of the sliding bar 2l isdrawn within the frame, and the eccentric 14 is also turned until itssmaller portion is presented to the pivoted bar 18, and the said bar isthen swung slightly outward, as shown in Fig. 2. Next the plug A isplaced in the receiving-section ct of the yoke, and before the plug isthus placed the heads of the plug are drawn outward in oppositedirections and pressed or flattened to lie as nearly as possible in linewith the stem 32. The sliding bar 2l is now run outward, and its jaw 24is brought at one side of the pressed plug, and the eccentric ismanipulated to force the jaw l9fagainst the opposite side of the plug.The plug will now be held in a flattened condition between the jaws 19and 24. The frame is again reversed, bringing the jaws to their ner faceof the tire, and upon withdrawing 6 fr;

the other jaw 19 the remaining portion of the heads will take a similarposition, completely closing the aperture in an air-tight manner.

Having thus described my invention, I claim as new and desire to secureby Letters 7o PatentM l. A tire-repairing tool,comprising a frame, and apair of jaws one of which is arranged to slide on the frame the otherbeing mounted to swing on the frame to and from the slid- 7 5 ing jaw.
